New XC 2 meter E-Tsotsi to challenge World Distance record.

After flying 3 distance flights this year ( 35km, 50km and 72km) I have gained lots of experience, and one thing that came out of this exercise is the fact that to go far you need lots of battery capacity, good penetration / glide angel ( more so when gliding) and a wing section that can carry the weight. On top of all this you need a powerful brush less motor that can swing a big prop with out robbing you from your precious battery
capacity. Talking about energy management!!!

With all this info I have now come up with the E-Tsotsi – mk2.
The airframe is still the same except that it is a little stronger and heavier and I have also made space for 4 X 2300 mh lipo 3 cell packs ( ruder and elevator servos are now mounted in the tail) all in parallel giving a total of 9200 mh.

I also fitted slightly less powerful motor 450Watt in place of a 550 Watt motor. From previous data it is possible to fly 40 to 50 Km per 2300 mh lipo pack depending on the conditions giving a theoretical distance of close to 200 km.

I still have to fly the maiden flight , and then if all goes well, tackle the paper work and planning for this flight. Hope my friend Evan and the rest of the team will be there to support me come the big day.
